Orioles pitching prospect Kevin Grendell, who was an 11th-round pick in June’s draft out of a California high school, has been suspended 50 games after testing positive for a banned substance called Dehydroepiandrosterone.

Grendell had been pitching in the rookie-level Gulf Coast League, where the left-hander got knocked around for 15 runs in 17 innings during his pro debut.

Because the minor-league season is over he’ll have to sit out the first couple months of next year.

According to my extensive Wikipedia research Dehydroepiandrosterone is a steroid hormone and the same drug NBA players O.J. Mayo and Rashard Lewis were suspended for using a few years back. It is legal to buy in the United States as a dietary supplement.
